MEMS In-Place Inclinometer
The Sanlien MEMS In-Place Inclinometer (IPI) is designed to measure lateral shifts in the ground or within structures.
It comprises a sequence of MEMS tilt sensors (uni or biaxial) mounted onto stainless steel tubing sections joined by universal joints.
MEMS IPI system includes the Smart Model, equipped with a data acquisition system for enhanced monitoring capabilities and streamlined data collection.
